Choosing COM: Key Factors to Consider

To explain simply, a COM is a small computer system established on an embedded development board. The module is known to include the most common software and hardware for coming up with any integrated product. Experienced system developers can exert attention to hardware (peripherals, display, and interfaces) and software (user interface and application) by utilizing an off-the-shelf com module and thereby speed up the time-to-market. There are multiple benefits of including a COM, but one must be aware of picking the suitable module by considering some key factors.

Processing or performance power

It is necessary to understand the requirement for optimal processing or performance power of an embedded application or product. Considering an IoT device, a small-scale Computer on a Module is more than enough compared to an AI-based device. When the embedded application involves Artificial Intelligence or AI-based, it demands high processing pr performance power to execute the task seamlessly.

Consumption of power

When an embedded product or application is designed and developed, the power consumption and heat production by the device/system must be considered. Power consumption in an embedded application is one of the vital criteria when selecting a SOM or COM. When a system is wired to a power source, like the mains electricity, power consumption restraints might be ignored. But, in the case of a mobile design, it is the power management on which the entire system relies.

Hardware restraints

The number of peripherals and the restraints related to it also play a vital role in picking a COM module. It is the responsibility of hardware developers and experts to recognize the presence of hardware peripherals like card readers, GPS, 4G, etc., on the carrier board. Based on their existence, a suitable com module must be chosen. This is an integral factor in selecting a COM or SOM and shouldn’t be ignored.

Compatibility of software

When it concerns reputed leaders in the processor market, comparing the availability of software and other tools is challenging. This is because the reputed brands in the processing market are used extensively. ARM-supported systems or devices benefit from functioning operating systems (Linux and Android operating systems) developed for mobile phones. On the other hand, Intel-backed systems or applications benefit from functioning in any operating system that can operate on Windows and Linux PC devices.


The developers and design experts need to assess the durability of COM or SOM. This is more so because manufacturers back the lifetime of a COM or SOM module for a specific time frame. When an embedded product or application is developed, a large part of its functioning depends on COM. Thus, it becomes necessary to consider the durability of the modules before picking one.


Whether one refers to it by SOM (System of Module) or com module, it is a powerful and compact device. A COM module adds excellent value to the design and development of embedded products and applications. Developers in the USA and around the world are optimizing the development of intelligent devices and IoT by including COM/SOM modules. Thus, it is essential to consider the factors mentioned above.
